Semiconductor quantum dots (QDs) feature excellent properties, such as high
quantum efficiency, tunable emission frequency, and good fluorescence stability.
Incorporation of QDs into new devices relies upon high-resolution and
high-throughput patterning techniques. Herein, we report a new printing technique
known as bubble printing (BP), which exploits a light-generated microbubble at
the interface of colloidal QD solution and a substrate to directly write QDs into
arbitrary patterns. With the uniform plasmonic hot spot distribution for high
bubble stability and the optimum light-scanning parameters, we have achieved
full-color QD printing with submicron resolution (650 nm), high throughput
(scanning rate of ?10(-2) m/s), and high adhesion of the QDs to the substrates.
The printing parameters can be optimized to further control the fluorescence
properties of the patterned QDs, such as emission wavelength and lifetime. The
patterning of QDs on flexible substrates further demonstrates the wide
applicability of this new technique. Thus, BP technique addresses the barrier of
achieving a widely applicable, high-throughput and user-friendly patterning
technique in the submicrometer regime, along with simultaneous fluorescence
modification capability.
